Remarks. This genus is distributed in East to Southeast Asia. As to the Vietnamese fauna one species of this genus, T. vietus Löbl et al., 1998 were described from Mt. Tam Dao, Vinh Phu Province, N Vietnam. This species collected from Mt Phia Oac was easily separated from T. vietus by the more sparsely and more weakly punctuated head and pronotum as shown in Fig. 4.
